[0002] Backwashing is a technique used to clean filtration systems, commonly found in water treatment. It involves using flowing water or other media to flush out impurities, particulate matter, or contaminants accumulated in the filter media, thereby restoring the efficiency and performance of the filtration system.

[0003] After backwashing removes impurities accumulated in the filter media, these impurities are also discharged from the system with the backwash water flow, thus forming wastewater. The wastewater can then be treated again using wastewater treatment equipment, thereby achieving the effect of energy saving and recycling.

[0004] Through long-term observation, it has been found that existing wastewater treatment equipment produces wastewater with a high concentration of suspended solids after prolonged sedimentation. These substances are generally denser than water and, under the influence of gravity, gradually sink and accumulate at the bottom of the tank. This makes subsequent cleaning require the complete removal of liquid from the tank, which presents a certain inconvenience. Therefore, an energy-saving backwash wastewater recovery device is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figure 1-5As shown, an energy-saving backwash wastewater recovery device includes a base 1; a treatment tank body 11 is fixedly connected to the top of the base 1; two sets of supports 12 are fixedly connected to the outer wall of the treatment tank body 11; a first spring rod 13 is fixedly connected to the inner wall of the supports 12; a support plate 14 is fixedly connected to the output end of the first spring rod 13; a sliding rod 15 is fixedly connected to the middle of the support plate 14, and the sliding rod 15 is slidably disposed on the inner wall of the treatment tank body 11; a cover 16 is fixedly connected to the bottom of the sliding rod 15, and the cover 16 is flared; a first sealing gasket 17 is fixedly connected to the bottom of the cover 16; multiple sets of connecting parts 18 are slidably connected to the middle of the treatment tank body 11; an elastic element 19 is fixedly connected to the inner wall of the connecting parts 18, and the elastic element 19 is further... One end is fixed to the inner wall of the treatment tank body 11; a tray 110 is fixed to the bottom of the connector 18; a second sealing gasket 111 is fixed to the side wall of the tray 110; multiple sets of first top rods 112 matching the shape of the connector 18 are fixed to the outer wall of the first sealing gasket 17; during operation, after fixing the base 1 in the designated working area, the operator can discharge external wastewater into the treatment tank body 11 from the inlet pipe on the side wall of the treatment tank body 11 until the wastewater volume in the treatment tank body 11 reaches a certain amount, allowing the wastewater to undergo long-term sedimentation treatment in the treatment tank body 11. After the wastewater in the treatment tank body 11 becomes stratified, the operator can simultaneously activate two sets of first spring rods 13 to open. The switch closes, allowing its output end to move quickly, and simultaneously causing the slide bar 15 to slide against the inner wall of the treatment tank body 11 until the flared cover 16 gradually approaches the bottom area of ​​the treatment tank body 11. Multiple sets of first push rods 112 at the end of the cover 16 gradually approach the top of the connector 18, so that after contact, they press the connector 18 downwards, simultaneously pressing the tray 110 downwards. This ensures that the first sealing gasket 17 at the bottom of the cover 16 fully contacts the inner wall of the treatment tank body 11, allowing the tray 110 to unfold between itself and the treatment tank body 11. This allows the cover 16 to partially block clear water inside the treatment tank body 11, while the unfolded tray 110... The turbid wastewater can be discharged. After the first spring rod 13 drives the cover 16 to reset, under the action of multiple sets of elastic elements 19, the tray 110 and the treatment tank body 11 can be closed again. This step, together with the cover 16, can reduce the troublesome problem of having to empty all the liquid in the treatment tank body 11 when the wastewater that has settled in the treatment tank body 11 needs to be treated later. At the same time, under the action of the first sealing gasket 17 and the second sealing gasket 111, the stability of sealing the bottom of the treatment tank body 11 can be improved, reducing the problem of partial liquid leakage. In addition, under the flared effect of the cover 16, the cover 16 can reduce the obstruction of some wastewater or impurities.

[0026] like Figure 1-5As shown, a rotating shaft 2 is rotatably connected to the center of the tray 110; a second spring rod 21 is rotatably connected to the inner wall of the rotating shaft 2; a handle 22 is fixedly connected to the output end of the second spring rod 21; two sets of locking blocks 23 are fixedly connected to the center of the handle 22, and the locking blocks 23 are set to match the shape of the bottom inner wall of the tray 110; multiple sets of scrapers 24 are fixedly connected to the side wall of the rotating shaft 2, and the two sets of scrapers 24 are in contact with the top of the tray 110; during operation, because the rotating shaft 2 is set in the center of the tray 110, after the tray 110 is unfolded, the operator can pull the handle 22 outward, which will stretch the output end of the second spring rod 21, and the two sets of locking blocks 23 can be separated from the recessed area at the top of the tray 110. Then, the handle 22 can be rotated to scrape off the sludge accumulated on the top of the tray 110, along with the two sets of scrapers 24. After that, a centralized cleaning can be carried out. After the handle 22 is used, the support for the handle 22 can be released again, and the handle 22 can be pulled back to its original position with the help of the second spring rod 21. This step, together with the two sets of scrapers 24, can improve the cleanliness of the top of the tray 110 and reduce the problem of some sludge adhering to the top of the tray 110 being difficult to clean. At the same time, with the locking block 23 sinking into the inner wall of the tray 110, the unused two sets of scrapers 24 can be fixed in position, reducing the problem of the scrapers 24 rotating when placed and stirring up the settled wastewater to make it turbid.

[0027] like Figure 1-5 As shown, the inner wall of the tray 110 has multiple sets of movable grooves 3; the inner wall of the fixed plate 4 is provided with magnetic balls 31; the side wall of the scraper 24 is fixed with a magnetic block 32, and the magnetic block 32 and the magnetic balls 31 are attracted to each other; during operation, the magnetic balls 31 are provided on the inner wall of the tray 110, and the scraper 24 can simultaneously drive the magnetic block 32 on its outer wall to rotate during rotation. When the magnetic block 32 approaches the designated position of the magnetic ball 31, the two can generate an attraction force, causing the magnetic ball 31 to hit the inner wall of the tray 110, which also has a vibration effect. This step, together with the magnetic balls 31, uses their continuous impact to clean the impurities clumped on the top of the tray 110, and works with the scraper 24 to clean them. At the same time, the movable grooves 3 can continuously change the working position of the magnetic balls 31 and play a multi-angle knocking role.

[0028] like Figure 1-5As shown, multiple sets of fixing plates 4 are fixed to the inner wall of the main body 11 of the treatment tank; a second top rod 41 is fixed to the middle of the fixing plate 4; multiple sets of support members 42 are fixed to the top of the cover 16; multiple sets of elastic plates 43 are fixed to the side wall of the support member 42, and the elastic plates 43 are set close to the second top rod 41. During operation, the support member 42 is set on the top of the cover 16, which can support the multiple sets of elastic plates 43. When the cover 16 rises or falls, the second top rod 41 can contact the multiple sets of elastic plates 43 in sequence. After the two are in contact, the elastic plates 43 can be reset and shaken. This step, under the action of the second top rod 41 contacting the elastic plates 43, can speed up the cleaning of residues on the surface of the cover 16 and reduce the problem of long-term accumulation of residues, which makes the top of the cover 16 rough and affects the subsequent underwater flow.

[0029] like Figure 1-5 As shown, multiple sets of reinforcing rods 5 are fixed to the inner wall of the processing tank body 11; a scraper 51 is fixed to the end of each reinforcing rod 5, and the inner wall of the scraper 51 is in contact with the sliding rod 15; during operation, multiple sets of reinforcing rods 5 are provided on the inner wall of the processing tank body 11, and the scraper 51 can be used to clean the sliding rod 15, and the cleaned impurities can fall into the processing tank body 11. This step, together with the reinforcing rods 5, can improve the cleanliness of the surface of the sliding rod 15 and reduce the problem of some impurities accumulating at the connection between the processing tank body 11 and the sliding rod 15 and causing subsequent jamming.

[0030] like Figure 1-5 As shown, a friction element 6 is fixedly connected to the end of the first push rod 112. During operation, by providing the friction element 6 at the end of the first push rod 112, the first push rod 112 can directly contact the connecting member 18 when it is pressed down. Under the action of the friction element 6, this step can increase the friction force generated after contacting the connecting member 18 and reduce the problem of slippage between the two.

[0031] Working principle: After fixing the base 1 to the designated working area, the operator can discharge external wastewater into the treatment tank body 11 through the inlet pipe on the side wall of the treatment tank body 11 until the wastewater volume in the treatment tank body 11 reaches a certain level, allowing the wastewater to undergo long-term sedimentation treatment. Once the wastewater in the treatment tank body 11 has stratified, the operator can simultaneously activate two sets of first spring rod 13 switches, causing their output ends to move rapidly and simultaneously causing the slide rod 15 to slide against the inner wall of the treatment tank body 11 until the trumpet-shaped cover 16 gradually approaches the bottom area of ​​the treatment tank body 11. The multiple sets of first push rods 112 at the end of the cover 16 can gradually approach... The top of the connector 18 allows it to press downwards after contact, simultaneously pressing the tray 110 downwards. This ensures that the first sealing gasket 17 at the bottom of the cover 16 fully contacts the inner wall of the treatment tank body 11. The tray 110 can then unfold between the tray and the treatment tank body 11, allowing the cover 16 to partially trap clear water inside the treatment tank body 11. Simultaneously, the unfolded tray 110 can discharge turbid wastewater. Afterwards, the first spring rod 13 resets the cover 16, and under the action of multiple elastic elements 19, the tray 110 can be closed again between the tray and the treatment tank body 11. A pivot 2 is located in the middle of the tray 110, allowing the tray 110 to... After unfolding, the operator can pull the handle 22 outward, extending the output end of the second spring rod 21 and separating the two sets of locking blocks 23 from the recessed area at the top of the tray 110. Then, the handle 22 can be rotated, and the two sets of scrapers 24 can be used to scrape away the sludge accumulated at the top of the tray 110. Afterward, a concentrated cleaning can be performed. After use, the support for the handle 22 can be released, and the handle 22 can be pulled back to its original position using the second spring rod 21. Because magnetic balls 31 are installed on the inner wall of the tray 110, the rotation of the scrapers 24 synchronously drives the magnetic blocks 32 on its outer wall to rotate. When the magnetic blocks 32 approach the designated position of the magnetic balls 31, the two... It can generate suction force, causing the magnetic ball 31 to strike the inner wall of the tray 110, and at the same time, it has a vibration effect. By providing a support member 42 on the top of the cover 16, it can provide positional support for multiple sets of elastic plates 43. When the cover 16 rises or falls, the second push rod 41 can contact multiple sets of elastic plates 43 in sequence. After the two are in contact, the elastic plates 43 can be reset and shaken. Multiple sets of reinforcing rods 5 are provided on the inner wall of the treatment tank body 11, and the sliding slide rod 15 can be cleaned by the scraper 51, and the cleaned impurities can fall into the treatment tank body 11. By providing a friction member 6 at the end of the first push rod 112, the first push rod 112 can directly contact the connecting member 18 when it is pressed down.
